SPRING-MOTOR.

Specification of Letters Patent.

Original application filed March 22, 1916, Serial No. 85,882. Divided and this application filed Jilly 15, 1916.

Serial No.

To all whom it'mayconocm Be it known that I, FRANK MAGIDSON, a citizen of the United States, and resident of Brownsville, in the county of Fayette and State of Pennsylvania, have invented certain' new and useful Improvements in Spring-Motors, of which the following is a specification. y I I This is a division of my application filed March 22, 1916, Serial No. 85,832, and the primary object thereof is to provide a spring motor of improved construction which while designed primarily for coti'perating with a vibrating escapement mechanism, the power of the motormay be variously utilized without regard'to the means employed for controllin the'unwinding of the motor spring.

In t e accompanying'drawings, Figure 1 is a longitudinal sectional elevation of spring motor mechanism embodying the invention. {Fig} 2is across section taken on line 2-2 of Fig. 1. Fig. 3 is alongitudinal section of one end of "the mechanism, the section through the escapement device bein taken at right angles to the position thereo shown in Fig. 1. Fig. 4 is a cross sectional elevation on line 4-4 of Fig. 1. Fig. 5 is a detail view of the washer-like element interposed between the core sections.

Referring to the drawings, the motor mechanism to which the present invention is directed is preferably arranged within an elon ated casing 2 of" rectangular form whic may be supported in any suitable manner with reference to the inechanism to be actuated by the motor. The'casing is closed at one end by head 3 in which is formed a bearin for the short shaft 4, the squared extremity 4' of the latter being adapted to receive a crank for winding up the motor.

Secured to the inner end of shaft 4; is sprocket wheel 5, and projecting inwardly from this wheel is the core or spool-like support for the elongated'coiledmotor spring 6. This spool orcore is formed in sections, 7 being the end section secured by lugs 8' and pin 8' to the inner side'of wheel 5.

9 designates the inner end section of the core which is non-rotatabl supported b pin 10 disposed diagonally 1n casing'2 with its extremities confined in the casing angles as shown.

'Between the opposite end sections 7 and 9 of the core aretheintermediatesections 11 which are rotatable on a rod or shaft 12 extending therethrough with the opposite ends 'ofthe rod grooved at 12 and rotatably confined in core sections 7 and 9 by screws 13. Thus it will be seen that the only non-rotatable portion of the core is the innermost section 9, the opposite end section 7 and the intermediate sections 11 being rotatable relative to each other. As rod 12 is itself rotatably held, the movable spool sections may rotate either with the rod or independently thereof. By this means every possible facility is provided for preventing the motor spring 6 when wound up from deflecting laterally and so gripping and binding the core as to interfere with a uniform and regular application of spring force to the driven mechanism. Thus, even if the lateral deflection Ofthe spring at one point tends to grip one section of the core, the remaining sections are in nowise affected and may turn freely in response to the unwinding action of the spring.

Interposed between the adj acent spool sections are the washer-like plates or heads 14 having their edges notched and with the resulting point-like projections 14 bent or deflected in opposite directions to overhang the adjacent spool sections, thereby bridging the joint between the latter andpreventing convolutions of spring 6' from working therebetween which if permitted might result in clogging the mechanism and impairing the operation. Partslareloosely arranged andmay turn with the spool sections, or it impinged by the spring may be held against turning, without retarding the operation.

The means for controlling the spring and for transmitting its power to the device to be actuated may be variously embodied. In the adaptation here shown said mechanism is so arranged as to transmit movement to a cradle, churnor other vibrating body. The controlling mechanism coiiperates with ratchet wheel 5, and consists of two levers 15 and 16 arranged at opposite sides of shaft 4 and extending past opposite portions of the ratchet wheel periphery. These levers are pivoted at their mner ends at 15' and 16, respectively, to a plate 17 secured to the annular boss 3 of easing head 3. The levers are connected for unitary movement by the bodily mowahle ningdikg link 18 which encircles shaft 4, with arm 19 projecting from lever 15 pivote to said linkat 19", and a similar arm 29 proj'ecting from the opposite side t lever 16'and' pivotally connected at 20 to link 18. The free extremity 15 of lever 15 extends through a slot in casing 2 and may be connected in any suitable manner, not shown, to the part or body to which vibrating, movement is to be;

transmitted.

Pivoted to levers 15 and 16 are the oppositely disposed dogs or pawls 21 and: 22

which are adapted to engage, the notches oi wheeli as in Figs 1 and Z'. A springQ-B connects dog- 21; with pivot post of; level; 15 and a like spring 24? similarly connects dog 22:with post, 16? of lever 16. With the parts thus, arranged, it will be: seen that movement oflevers 15 and 16 ineither di rection from a straight line, position will place the springs 23 and 24;; under: tension which results in moving dogs 21: and 22 either into; or out of engagement with the teeth of wheel 5, depending onthe directionzof movement oi the levers; Thus, with the levers in the position shown in Big; 1:, the movement of lever Iii-toward; the. felthas resulted in so deflecting. spring: 23: as to cause dog 21 to engage the ratchet as seen in 2, and at the same time the opposite deflection of spring: has resulted: a reverse movement of dog- 22?, thereby disen; gaging the latter from the; ratchet: wheeh The movements thus described result from the arrangement whereby the free portions as the spiring connected levers; 1:5, and 16 move simultaneously in the same direction, first toward one side of the casing and then tow'ardvthe opposite side.

Upon stopping the vibration of the bodiy to which lever 15 is connected, the dog carrying levers hold the mechanism: still or inoperative until the body; is again started to swing, where-upont-lee escapeinent w'ilil im mediately become active and continue to operate until the bodyis; againsteppedw or untilthe motor has become completely unwound;
